So how do you buy clothes without trying them on first? It's a lot simpler than it sounds. We've put together a few useful tips which will help you choose the right size for you.

Neck size

Use measuring tape to measure around the base of your neck, with a finger sized gap between the tape and your neck. Use this measurement to find the corresponding size in the size chart.

Chest

Use measuring tape to measure around the chest, with the tape placed under the armpit. Find the corresponding size in the size chart.

Waist size

Measure the circumference of the waist, where your pants normally sit. Leave a finger-sized gap between the measuring tape and the body. Then check which size in the size chart corresponds to your measurement.

Shoe sizes

Castro uses the European sizing system. For your convenience, we've included a conversion chart for other sizing systems such as UK and US.
